Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575676, here are decompositions:

  • 5 + 31575671 = 31575676
  • 23 + 31575653 = 31575676
  • 113 + 31575563 = 31575676
  • 227 + 31575449 = 31575676
  • 239 + 31575437 = 31575676
  • 269 + 31575407 = 31575676
  • 443 + 31575233 = 31575676
  • 569 + 31575107 = 31575676

Showing the first eight; more decompositions exist.
